Prime Minister Scott Morrison has poked fun at himself while denying any knowledge of a dodgy Photoshop job which saw his weathered tennis shoes replaced with clean, white ones in an official photo.

Key points:

The PM said he would prefer if his lack of hair had been Photoshopped instead of his shoes

A spokesperson said Mr Morrison prefers his own shoes to the replacements

The website is now showing the real sneakers

The banner for the Prime Minister's official website features a photo of Mr Morrison and his family, but Twitter user Luke Martin noticed on Tuesday that the PM's white shoes were clearly a pasted-in addition.

Further investigating by the Twitterverse revealed an original version of the picture, showing Mr Morrison wearing a pair of well-loved K-Swiss sneakers instead of the Photoshopped crispy white Common Projects in the doctored version.

It was also pointed out by another user, Andre Serna, that the shoe on Mr Morrison's right foot was actually a left shoe.

In her resignation from politics, Kelly O'Dwyer said she feared another miscarriage in Canberra, far from home. Her announcement is shocking for more than just party-political reasons, writes Emma A. Jane.
